Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (1) 1__ ± The present invention relates to the scope of pumps, and particularly refers to a liquid level holding pump with automatic actuation and deactivation settings. Liquid pumps, such as a sewage pump and a puddle pump, are used in liquid level maintenance systems. In many structures, such as ships and homes, they are often used as safety equipment. Pumps in level maintenance systems can also be used in other applications, such as level maintenance between a predetermined minimum and maximum water level in a tank or tank. The sewage pump and puddle pump system usually tries to keep the water level in the structure to a minimum to reduce or eliminate water damage to the structure. Some known systems use a water level detection device to activate and deactivate the pump motor. When the detection device determines that the water level has reached a predetermined maximum water level, the pump motor is activated. When the detecting device determines that the water level has fallen below a predetermined minimum water level, the pump motor is deactivated. In some systems, the same water level is used as both the lowest and lowest water levels. There are generally two types of liquid level detection devices used in these systems, one is an "open circuit detection device" and the other is a "closed circuit detection device." The open circuit detection device uses a device between two electrode terminals. The existence of an external conductive material completes a circuit through the conductive material between the two electrode terminals, and turns on and off the detection circuit of the system. That is, when an external conductive material is like, for example, water , Enter the open circuit detection device and electrically contact the electrode end of the detection circuit, and when the circuit is completed, the open circuit detection device causes the pump to be activated or deactivated. The detection of the liquid will usually cause the pump to cause However, it will also cause deactivation.

Description of the invention (2) or a combination of electrode terminals is used in the open circuit Detection device. In contrast, the closed-circuit detection device does not require an external conductive material to complete a circuit, and the detection circuit is actuated within the device. That is, all components that require electricity are included in a closed-circuit detection device. In the system, a sewage pump that uses a closed-circuit detection device is disclosed in US Patent No. 3,717,420 (Rachocki Chongzhong. The pump in Rachocki uses a pontoon mechanism to detect the water level in a vessel. The The buoy mechanism contains a magnet. When the water level rises, the buoy rises to a point where the magnetic field of the magnet causes a reed switch to be turned on. When the switch is turned on, the pump motor is activated and water is pumped away The vessel. When the water level drops, the buoy descends to actuate a constant temperature delay mechanism. After a delay time, the magnetic field is removed from the reed switch, the switch is turned off and the pump motor is deactivated. Rachockit One disadvantage of the disclosed sewage pump is that, due to the temperature of the delay mechanism, the fruit is susceptible to change. ** ''-. ".-T-a puddle using a closed-circuit detection device The driving system is disclosed. 1 In US Patent No. 5,234,319 (miikii), the puddle pump driving system also uses a buoy to detect the water level. The buoy is placed in a signal generator, which is similar to an analog signal generator. Associated. When the water level rises, the buoy rises and the signal generator causes the pump motor to cycle. However, this system suffers from some disadvantages. That is, because the system uses a signal float mechanism to actuate and disengage. Actuate the pump, due to small water level changes, the pump motor will perform a cyclic operation.

Invention Description (Automatic Control Mechanism for Pumps. The automatic control mechanism disclosed in these patents is a closed-circuit detection device, which is composed of a buoy, a magnet fixed on the buoy, and a reed switch. A check valve is provided around the top of the chamber surrounding the buoy and magnet to allow gas to flow out, but not into the chamber. When water enters the lower part of the chamber, the buoy and magnet rise and the reed switch is finally turned on. Air flows out through the one-way valve, and when the water level drops, a partial vacuum is created above the magnet on top of the chamber. The local vacuum prevents the magnet from descending along the water. When the water level drops below an air flow inlet contained in the lower part of the chamber, air enters the chamber and the magnet is lowered, allowing the motor to deactivate. One problem with this automatic control mechanism is that it relies solely on the local vacuum generation. Therefore, if the generated vacuum is insufficient, the magnet will drop with the water, causing the pump motor to cycle. If the vacuum is too strong, the magnet may not drop, causing the pump motor to run continuously. U.S. Patent Nos. 5,078,577 (11 ££) 1111 £ 〇1, 4,678,403 #. (Rudv £ l__ai), 4,171,932 (Millfii), and 4,205,237 are related to the use of an open circuit detection device. The liquid pump is composed of a conductive sensor that senses the water level, and therefore activates or deactivates the pump. The sensor is placed at a high water level. When water reaches the high water level and contacts the sensor, a conductive circuit is created between the sensors, which allows a current sensing circuit to actuate the pump motor. When the water drops below the high water level, the conductive circuit is eliminated and the pump motor is deactivated. These systems have disadvantages. These systems rely on sensors that must be immersed in the water to operate the system. The use of the sensor may be changed, corrupted or even destroyed,

Description of the Invention (4) Affects the conductivity of these sensors. In addition, water may contain a substance that affects the conductivity of these sensors, which can also prevent the pump from being activated. U.S. Patent No. 4,265,262 (Hating) relates to a pump control system for a water storage tank, which uses an open circuit detection device to detect the water level in the water storage tank. The system uses a pair of electrically conductive sensing probes at a high water level and a pair of electrically conductive sensing probes at a low water level. When the water level reaches the pair of electrically conductive sensors located at a high water level, the water storage tank is activated, and when the water level drops below the pair of electrically conductive sensors located at a low water level, the water storage tank pump is released. move. US Patent No. 4,766,329 (Santisg ^) also relates to a pump control system that uses an open circuit detection device to detect high and low water levels. Three probes are arranged in a staggered pattern so that one probe is at a high water level, one second probe is at a low water level, and one third probe is at a position lower than the low water level. When water rises to the high water level probe, all three probes come into contact with the water, thus creating a conductive path that excites a relay to actuate the pump. When the water level drops, a conductive path is created between the low water level probe and the third probe, which excites a holding circuit to keep the pump running. When the water level drops below the low water level probe, the conductive path is eliminated and the pump stops actuating. However, these systems, like one above, rely on probes that must be immersed in salt water to operate the pump. These used probes may become dirty, corroded or even destroyed, affecting the conductivity of these probes. In addition, water may contain a substance that affects the conductivity of these probes, which can also prevent the pump from being activated.

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 477862 V. Description of the Invention (5) A device and an electrical state sensor to activate and deactivate a sewage pump motor. At a predetermined time, the timer sends a signal to actuate the pump motor. Once activated, the condition sensor probes the load of the motor, which is an indicator of the amount of physical resistance experienced on the impeller of the pump due to the presence or absence of water <. If water is detected, the pump keeps pumping water out. If no water is detected, the pump is switched off. The No. 012 patent includes the use of a cyclic generator, which includes a timer and a generator. The timer activates the generator in a predetermined cycle. And the generator sends a signal to the motor to operate with a small part of its full power (so the motor has a small threat). Once activated, the state sensor detects the load of the motor as described above. US patent Case No. 4,841,404 (Marshall £ Lai) also used a load sensor to deactivate an operating pump. However, these pumps have some disadvantages. First, in order to sense the load on the motor, the motor must be turned on. The motor's cyclical action generates noise, which may not be desirable, especially at night. In addition, the use of a timer to actuate the pump may be less efficient than a mechanism that maintains the water level based on sensing information because the timer cannot take into account a change in state, such as, for example, a large amount of water flowing in. The aforementioned testing agencies use different "testing standards" to determine the level of actuation and deactivation. These standards include, but are not limited to, sensing the load on a running motor to detect the water level. The water level uses a float to activate a reed switch and sense a conductive path through the water. There is a need and desire for a liquid pump that uses a water level detection mechanism to actuate and deactivate the pump, which will reduce the Pump motor cycle

The buoy assembly 40 is positioned in the chamber 41 and includes a buoy housing 48. The pontoon assembly 40 has a size that is slightly larger than that of a steel plate. A magnet 46 is mounted inside the buoy assembly 40. Preferably, the magnet 46 is located in the center of the buoy housing 48. The pontoon assembly 40 is formed of an appropriate material so that the overall density of the assembly 40 is smaller than that of water, so that it can float in water. The plurality of guide pillars 47 extend upright along the second wall portion 37 and the outer casing portion 20. As shown in FIG. 9, four of these pillars 47 are positioned in the chamber 41 such that two pillars 47 are attached to one side of the pontoon assembly 40 and the other two pillars 47 are attached to the first two pillars 47. The opposite side. The spacing and adjustment of other pillars 47 may be used. The pillars 47 help the alignment of the buoy assembly 40 inside the chamber 41, so that when the water level inside the chamber 41 repeatedly rises and falls, the magnet 46 maintains a reed switch provided on the PCB 58 42 lined up. In addition, the pillars 47 prevent the buoy assembly 40 from being blocked inside the chamber 41 because the pillars 47 prevent the buoy assembly 40 from being excessively tilted. In addition to the pillars 47, the chamber 41 includes two circular bases 45, which also assist in the alignment of the pontoon assembly 40 inside the chamber 41. The PCB 58 is bonded to the printed circuit board housing portion 52 and the buoy chamber 41 by a thermal pile positioned in the bases 45. The pontoon chamber wall 25 is also bonded to the pontoon chamber 41 by screws 51 positioned in the bases 45. Screws 51 are inserted into the bases 45 to clamp the nozzle frame 22 to the chamber 41. The reed switch 42 is erected above the buoy assembly 40 and is fixed to the PCB 58. The PCB58 is adjacent to the motor housing area. 16 This paper size is applicable to China National Standard (CNS) A4 specifications (210 X 297 mm). 15 ------------- Installation ------ --Order --------- line (Please read the precautions on the back before filling this page) 477862 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ___B7____ V. Printed Circuit Board of Invention Description (13) The case portion 52 is supported. The buoy assembly 40 and the reed switch 42 cooperate to connect the motor 12. Water enters the pump 10 through the holes 23 and 35 and the elongated hole 39. Because the density of the buoy assembly 40 is smaller than that of water, when water enters the chamber 41 through the elongated hole 39, the buoy assembly 40 will rise with the water. Because the water level continues to rise ', the magnet 46 moves close to the reed switch 42. The magnet 46 will eventually move close enough to the reed switch 42 so that the reed switch 42 will interact with the magnetic force of the magnet 46 close to the switch 42. Once approached, the circuit on the PCB 58 actuates the motor 12. A description of the circuit contained on the PCB 58 will be provided with reference to FIG. The impeller 14 is engaged by the actuating motor 12.

The actuation circuit 80 includes the reed switch 42, first, second, third, and fourth resistors 81, 82, 83, 86, a second diode 84, and a first Comparator 85. The reed switch 42 is connected to a ground voltage and a first input 85a of the first comparator 85. The second diode 84 is connected to the voltage V2 and the reed switch 42. When the reed switch 42 is normally open, a floating voltage is present at the first input terminal 85a of the first comparator 85. When the magnet 46 (see FIG. 8) is moved close enough When the reed switch 42 is turned on, the reed switch 42 will be turned on due to the combined effect of the magnetic force of the magnet 46, and the first input paper size connected to the first comparator 85 applies the Chinese National Standard (CNS) A4 specification ( 210 X 297 public love) 17 477862 Printed by A7 B7, Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (15) The input terminal 85a is connected to the ground. The first resistor 81 is connected to the second supply voltage V2 and the Between a second input terminal 85b of one of the first comparators 85. The second and third resistors 82, 83 is connected between a ground voltage and the output terminal of the first comparator 85 to form a feedback circuit from the second input terminal 85b. The configuration of the first, second, and third resistors 81, 82, and 83 A reference voltage is provided at the second input terminal 85b of the first comparator 85. When the reed switch 42 is turned off 'the reference voltage will be less than the floating voltage at the first input terminal 85a, but when the spring When the leaf switch 42 is turned on, it is greater than the ground voltage. In operation, the output of the first comparator 85 remains low until the reed switch 42 is turned on. When the reed switch 42 is connected During the on time, the voltage at the second input terminal 85b is greater than the voltage at the first input terminal 85a, so the output terminal 85c of the first comparator 85 reaches a high potential. The output terminal 85c of the first comparator 85 is regarded as a uniform operation signal of the pump. As will be described below, the trigger circuit 90 is used to excite the first transistor 066 and actuate the pump motor 12. The fourth resistor 86 acts as a limiting resistor, which ensures that the output terminal 85c is used at an appropriate potential for other parts of the circuit of the PCB 58. The voltage sensing resistor 104 is connected to the negative terminal of the sewage pump motor 12. When the pump motor 12 is operating, a current flows through the voltage sensing resistor 104, which generates a voltage corresponding to the load on the operating motor 12. As will be discussed below, when water is pumped at a high water level, the load on the motor 12 rises, and therefore, the voltage across the voltage sensing resistor 104 increases. When water is pumped at a low water level, the load on the motor 12 is reduced, so the voltage across the voltage sensing resistor 104 is reduced (the Chinese National Standard (CNS) A4 specification applies to this paper scale ( 210 X 297 Meal) I 1- IH ϋ H ϋ n ϋ nn nn ϋ »ϋ n ϋ II ϋ I I * J« I · 1 ϋ ϋ ϋ II IIIII ι IIII 1 I ϋ ϋ ϋ I ϋ I ni ϋ ϋ ϋ · (Please read the precautions on the back before filling this page) 18 Ministry of Economic Affairs. «Printed by the Consumer Affairs Cooperative of the Property Bureau 477862 A7 B7 V. Invention Description (16) is called" low water level voltage "). When water is pumped by the motor 12 at a low water level, the pump deactivation circuit 98 is connected to the voltage sensing resistor 104 and generates a deactivation signal. The pump deactivation circuit 98 includes a reference circuit 94, a second comparator 100, a third diode 101, a seventh resistor 102, and a second capacitor 99. The reference circuit 94 includes fifth and sixth resistors 95 and 96 connected in series and connected between the second supply voltage V2 and the ground voltage. The series connection of the fifth and sixth resistors 95, 96 is used as the first input terminal 100a of the second comparator 100. The resistance values of the resistors 95 and 96 are selected so that a reference voltage equal to the low water level voltage exists at the first input terminal 100a of the second comparator 100. The reference voltage may be slightly lower than the low water level voltage to provide a small margin voltage to ensure that the water system inside the casing 30 is at a low water level. The first valley transformer 99 is connected between the second input terminal 100b of the second comparator 100 and the ground voltage. The second input terminal 10015 is also connected to the voltage sensing resistor 04 through the seventh resistor 102. Therefore, the voltage across the voltage sensing resistor 104 enters the input terminal of the second comparator 100. When the reference voltage (the first input terminal 100a) is lower than the voltage across the voltage sensing resistor 104 (the second input terminal 100b), the output terminal 100c of the second comparator 100 Is high. Once the voltage across the voltage sensing resistor 104 is lower than the reference voltage, the output terminal 100c of the second comparator 100 becomes a low potential (or a negative potential). This low-potential output is used as the pump deactivation signal, which is transmitted through the third diode 101 to the trigger circuit 90.

Description of the invention (17) When the signal is activated, turn off the pump motor 12 First transistor i〇6. The trigger circuit 90 is connected to the first transistor 106, the pump actuation circuit 80, and the pump deactivation circuit 98. The trigger circuit 90 excites the first transistor 106 and, accordingly, activates the pump motor 12 in response to the actuation signal. The trigger circuit 90 will turn off the first transistor 106 and, accordingly, turn off the fruit motor 12 corresponding to the deactivation signal. The trigger circuit 90 includes a second transistor 92 and an eighth resistor 91. The second transistor 92 may be an npn-type switching transistor that is driven by a single (or positive) voltage. The second transistor 92 and the eighth resistor 91 are connected in series between the second supply voltage V2 and the ground voltage. The series connection is in turn connected to the gate terminal of the first transistor 106 at a contact 93. The contact% is regarded as the output of the trigger circuit 90. The operation of the trigger circuit 90 is described below. When the actuation signal is received from the actuation circuit 80, the second transistor 92 is triggered. Once triggered ', the first transistor 92 pulls the voltage at the contact 93 to ground. Therefore, a low voltage is applied to the first transistor 106, and the first transistor 106 becomes excited and activates the pump motor 12, because the first transistor 106 is caused by a low voltage move. When a deactivation signal is received from the deactivation circuit%, the second transistor 92 is turned off. It should be noted that at this time the δ deactivation ^ will not exist, because the water has dropped to a level lower than a level that would cause the magnet 46 to approach the reed switch 42. Once the second transistor 92 is turned off, the voltage across the eighth resistor 91 is present at the contact 93. This is a high voltage acting on the first transistor 106. Therefore, the first transistor 106 is turned off because the first transistor 106 is addicted (please read the precautions on the back before filling in this Page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs --- ^ --------- ^ IAW ----------------------- --20 477862 A7 V.

The pump 10 utilizes a separate deactivation mechanism that includes a sensor 104 that detects a load on the pump motor 2 and, when the detected load is indicated on the pump housing 3o. When the internal water has reached a low level, the motor 12 is deactivated. By using a deactivation mechanism separated from the activation mechanism, the pump 10 of the present invention prevents the motor 12 from being excessively circulated. By avoiding the use of conductive sensors that must be immersed in salt water, the actuation and deactivation mechanism of the sewage pump 10 is able to resist the extreme environment of bilge sewage of a vessel, in particular, due to salt water problems. In addition, by using a pontoon assembly 40 serving as the actuating mechanism, the sewage pump 10 detects the water level in the bottom of a vessel to take into account sudden changes such as, for example, a large amount of water Inflow.
